Method and device for detecting configuration and violation of policy of terminal in wireless communication system

Abstract

The present disclosure relates to a 5 th generation (5G) or 6 th generation (6G) communication system for supporting a higher data transmission rate than a 4 th generation (4G) communication system such as long-term evolution (LTE). A method performed by a network data collection and analysis function (NWDAF) in a wireless communication system may comprise the steps of: receiving, from a policy control function (PCF), user equipment (UE) route selection policy (URSP) information relating to a UE policy to be applied to a UE; requesting session information that is being used by the UE, on the basis of the URSP information; requesting a report on traffic information for each application used by the UE on the basis of the URSP and the session information; and receiving the traffic information for each application from the UE.

         16 . A method performed by a network data collection and analysis function (NWDAF) entity in a wireless communication system, the method comprising:
 receiving, from a policy control function (PCF) entity, first information requesting analytics for user equipment (UE) traffic;   transmitting, to a network entity, a message requesting data for the analytics;   receiving, from the network entity, second information associated with the UE based on the message;   generating the analytics for the UE traffic based on the second information; and   transmitting, to the PCF entity, the generated analytics.   
     
     
         17 . The method of  claim 16 ,
 wherein the first information includes a UE identity (ID), an analytics ID, and an application ID,   wherein the second information includes the UE ID, a single network slice selection assistance information (S-NSSAI), and a data network name (DNN).   
     
     
         18 . The method of  claim 16 ,
 wherein the analytics includes third information on the UE traffic,   wherein the third information includes at least one of information on a UE selection policy (URSP) or information on traffic descriptor.   
     
     
         19 . The method of  claim 16 ,
 wherein the network entity includes at least one of a session management function (SMF) entity or a user plane function (UPF) entity.   
     
     
         20 . A method performed by a policy control function (PCF) entity in a wireless communication system, the method comprising:
 transmitting, to a network data analytics function (NWDAF) entity, first information requesting analytics for user equipment (UE) traffic;   receiving, from the NWDAF entity, the analytics for the UE traffic,   wherein the analytics for the UE traffic is based on second information collected for the analytics.   
     
     
         21 . The method of  claim 20 ,
 wherein the first information includes a UE identity (ID), an analytics ID, and an application ID,   wherein the second information includes the UE ID, a single network slice selection assistance information (S-NSSAI), and a data network name (DNN).   
     
     
         22 . The method of  claim 20 ,
 wherein the analytics includes third information on the UE traffic,   wherein the third information includes at least one of information on a UE selection policy (URSP) or information on traffic descriptor.   
     
     
         23 . The method of  claim 22 , further comprising:
 generating fourth information applying for the UE traffic based on the analytics; and   transmitting the fourth information is associated with at least one of an updated URSP or an updated traffic descriptor.   
     
     
         24 . A network data collection and analysis function (NWDAF) entity in a wireless communication system, the NWDAF entity comprising:
 a transceiver, and   a controller coupled with the transceiver and configured to:
 receive, from a policy control function (PCF) entity, first information requesting analytics for user equipment (UE) traffic; 
 transmit, to a network entity, a message requesting data for the analytics; 
 receive, from the network entity, second information associated with the UE based on the message; 
 generate the analytics for the UE traffic based on the second information; and 
 transmit, to the PCF entity, the generated analytics. 
   
     
     
         25 . The NWDAF entity of  claim 24 ,
 wherein the first information includes a UE identity (ID), an analytics ID, and an application ID,   wherein the second information includes the UE ID, a single network slice selection assistance information (S-NSSAI), and a data network name (DNN).   
     
     
         26 . The NWDAF entity of  claim 24 ,
 wherein the analytics includes information on the UE traffic,   wherein the information includes at least one of information on a UE route selection policy (URSP) or information on traffic descriptor.   
     
     
         27 . The NWDAF entity of  claim 24 ,
 wherein the network entity includes at least one of a session management function (SMF) entity or a user plane function (UPF) entity.   
     
     
         28 . A policy control function (PCF) entity in a wireless communication system, the PCF entity comprising:
 a transceiver, and   a controller coupled with the transceiver and configured to:
 transmit, to a network data analytics function (NWDAF) entity, first information requesting analytics for user equipment (UE) traffic; 
 receive, from the NWDAF entity, the analytics for the UE traffic, 
   wherein the analytics for the UE traffic is based on second information collected for the analytics.   
     
     
         29 . The PCF entity of  claim 28 ,
 wherein the first information includes a UE identity (ID), an analytics ID, and an application ID,   wherein the second information includes the UE ID, a single network slice selection assistance information (S-NSSAI), and a data network name (DNN).
